This map was created during my tenure with the DensityDesign team at the Politecnico di Milano using open data from the council of Milan, Italy. The visualization shows the distance between secondary schools and the city centre of Milan, which is represented in this information graphic by the Duomo – the city’s most famous landmark. Each school is visualised using a circle with a diameter that correlates with the size of its student body.

Milan is usually represented by concentric rings starting from its most famous landmark, the Duomo. So, each dot shown on this map is connected to its centre by a line measuring the distance between the Duomo and each respective school. The map is based on the analogy that if Milan was a planet, schools would constitute its satellites.
